CCleaner is a system optimization, privacy and cleaning tool. It removes unused files from your system - allowing Windows to run faster and freeing up valuable hard disk space. It also cleans traces of your online activities such as your Internet history. Additionally it contains a fully featured registry cleaner. But the best part is that it's fast (normally taking less than a second to run) and contains NO Spyware or Adware!

In version 5.04, we've added a feature to ignore new files in your custom cleaning options which is great for the temporary folders of your favorite apps! We've also improved support for smaller screen sizes along with improved user account control skipping functionality. Along with this we've optimized the algorithm for detecting system restore points!"

"In this release we've focused on introducing support for the new browser Microsoft Edge... Spartan or Internet Explorer 12 as some of you may know it. We've also added browser cleaning improvements for Firefox and Google Chrome along with improving our system restore detection algorithm. And as always, the team has been fixing bugs and making a host of performance and GUI improvements!"

"Since last month, when we concentrated on improving browser cleaning, we've been working hard adding support to uninstall Windows Store apps.

We certainly haven't forgotten about browsers though, as we've also improved Chrome and Firefox cleaning. Support for the latest Microsoft Office 2016 has also been introduced and our translations have been updated to ensure we're speaking the local lingo correctly."
